Recently there was this guy, a dumb jock type, who tried to write his own prenup and then showed it to his lawyer... believe it or not, one of the things the guy tried to include in it was a stipulation that his wife "must give him a minimum of X# of bj's every year"... the lawyer told him to take that part out, and of course the guy whined, but finally complied. The funny part was, he wasn't doing it to be a smart ass or trying to be tongue in cheek, he was being deadpan serious!!!
Oh well, it always tended to be the less intelligent grades of guys that go in for the oral thing...
